This invention relates to a new and im# proved transferring device for use with loose leaf binders Vof the type usually designated as ring binders, and 'is particularly designed for use with such binders when the same are to be used as a visible index.

l/Vhen loose leaf binders are used as a visiof. When this is done it is necessary to move upwardly the sheets which were positioned. next below the sheet which was removed. In order to accomplish this operation quickly and easily itis desirable to have somemeans whichwill direct the movement of a sheet laterally in the binder and yet which 'will at the same time function as a retaining means for the sheet. rIhis is particularly desirable when a plurality of sheets are to be moved for it obviates the necessity of taking them from one setof prongs and placing them on another set of prongs 'with the liability of the sheets becoming disarranged so that holes provided in them kwill not be in registration.

The main object vof my invention is to provide a device which may be used with a loose leaf binder as desiredr and which will direct and facilitate the transfer of sheetsfrom one set of prongs of the binder-toanother set of prongs and during the operation cause the sheets to move laterally in the book.

Another object ofl my invention is to provide a means of the character described which can be used interchangeably with a plurality of loose leaf binders. y

Otherobjects and advantages relate to the size and shape of my device and the means provided forits easy and convenient use with different types'of loose leaf binders all as' will more fully appear from the followingdef scription taken in connection with the ac' companying drawings inwhichtV Figure l is a top plan view of a binder with the prongs in the open position( and with my device assembled the binder, the covers of the binder being partially broken away.

Figure 2 is an end view of a binder which I have-shown as a binder with which my device may be utilized, the prongs of the binder being' in the closed position.` Y

Figure 3 is a view similar to Figure Q with the prongs of the binder in the openposition.

Filgure l` is a section on line 4.1`4'of Figure Figure 5 is a perspective view of my device.`V

It will be understood that my device may be utilized with loose leaf binders of different i designs but for the purpose of illustratingthe design and functioning of my structure I have here shown a binder of a specific type composed of back members .-1- andk ,-2-- hingedly connected on' their'inner longitudinal edges` by hinges 3; and l- Back member -1- carriesaback plated-#- ,ex

tending vertically above its cuterv longitudinal edge. A top plate v--6`-v approximately rightangular in cross nsection is positioned on the upper face of back memberl-J-ln spaced relation to back plate .-5- nand is provided with an outwardly extending upper. face -7 registering with the upper edge of A cover plate a'-8- isv back plate -5-. positioned onrthe upper rand inner face of back member 1- and overlies top plate -6- to lock the same'inposition.

Similarly back member .2- isprovided with a back platee-9 and top plate 10.- having an upper portion V 11-` in registrav tion with the upper edge -of'back plate +9..-

and a cover plate -TIQ- allassembled inthe sameway as has Just beenl described` with Ilrgelation to the similar -membersonback memer,l-.

The upper faces f--f and4 -'-11' of i )backv plates -5--l and -g-9-.are each provided with a. plurality Vof holes 18-13V inlongitudinal spaced relation. Prongs 1&1@v are secured by welding or other convenient means in spaced relation in holes 13 13 inrupper face holes 13-13 in upper face l1 but are grouped in sets as lshown on Figure l and in *this case the end sets consist of two prongs each and the intermediate sets consist of three prongs and similarly the prongs 14e-14 in upperv face 1l will register with holes 18--13 in upper face -7-. r r

' For the'purpose of releasably holding the binder in the closed position or in the open position as desired I provide at both ends of backy members -1- and -2- a locking device and inasmuch as the locking devices at the opposite ends of back members land -2- are similar in construction a descriptiony of one will -be a description of both.V

My locking device may best be understood by referringto. Figures 2 and 3. A plate ^-.15# approximately' square in shape is any convenient means not shown and is provided with an outwardly extending lug Ay second plate -l'T-f is affixed to the end of back member -2-, plates -l5- and 17T-e being disposed in approximately the same plane, Plate '-17- is provided with a slot 718-- for a purpose hereinafter to be described. A locking `plate --19- is pivotally mounted inback member -2- by meanslof a. roc l1-70.- which extends longi tudin'ally through back member -2- and which isrotatably mounted therein. Locking plate- IQ-carries at one side of its pivot an elongated slot 2l coacting with lug --16--.v On the vother side of the pivot locking plate,-19- carries an outwardly extending tab -22- and a'tongue 23 extending inwardly through slot -18--. A spiral spring -24- is positioned onrod -----V abut-ting against the inner face of plate -l7- and' having one end in engagement with the under surface of tongue -23ftonormallyexert upward pressure on tongue Elongated slot 2lhas a recess '-25 at one end thereof and has at the other end a recess -26-'. lVhen the binder is in theclosed position as shown in Figure 2 the lug -l6 will be positioned in recess .-26- and may onlybe released therefrom by moving locking plate n'-19-- about its i plate -19- which is positioned at the opposite end ofthe binder is also rigidly secured -to an end of rod -20-- so that downward pressure on either of tabs -22- will cause a pligfotal movement of both the locking plates As perhapsfmay best be seen from Figure 5v my transferring device V--27- consists of a short rod preferably circular in crosssection and having both ends of the shape of a ytruncated cone as shown Vat -28- 'with a recess as -29- in each end. Recess 29-V is of a size and shape to receive the pointed ends -30- of prong llland 14.

As perhaps maybest be seen from Figure rl 'the length of my transferring member -27- is such that when one end is placed on a prong --14f the transferring'member f27 will extend obliquely across the binder -so that its other end will registery ordervto placeit in position between two prongs 14C-14 they must be sprung slightly apart so that when transferring member -27#- is in position it will be held therein by theresiliency of prongs lll-14.

VIn utilizing my transferring member that the length of transferring member -27 is such that in F-27-- the sheet or sheets #3l-having a plurality of holes -32- in spaced relation along one longitudinal edge thereof, are placed on one set of prongs -14-- andthe binder is then opened to the position shown in Figure 3. I then place in position my transferring member -27`- with one end in position on prong -M-f extending upwardly through sheet -31- and with its other'end in position on an opposing prong V-14-. It is preferablev when a transfer of sheets is to-be made to use a second transfern ring member 27-` coacting with a second prong -14.-- extending upwardly vthrough sheet -31 so thatthe sheet #3lwill be held in alined relation to. prongs -lli as thesheet is moved off from the prongsV eli-#14, on which it was initially positioned, onto the opposite set of prongs 11M-+14.

InFigure 1 4I havey showfin position one transferring device v--27-', in solid lines, anda second device in position7 in cross section, Q Blg.. v`--31- is raised upwardly from prongs 14T-14 onto transferring devices-27H27;- the sheets-31- will be moved obliquelyl of the binder into la position to move. ofi from I havealsoshown, :in solid lines, a sheet and it will bessen-that whenk sheet `llO Y transferring devices 27-27 onto the opposite set of prongs MEL-14. Having been guided in an oblique direction by transferring device 27-27, sheet -31- will have been moved laterally of the binder into the position shown in dotted lines on Figure 1.

The transfer of the sheet -31- having been completed the transferring devices 27-27 are removed from prongs lll-111 and the binder may then be closed.

It will be understood that the length of my transferring device -27- and that the number and position of prongs lll-14 may be varied so that the distance of the lateral movement of sheets 3lin the binder may be varied at will. For example, in the transferring operation just described I have shown a transferring device 27 of such a length that the sheet -31- will be transferred from a prong 14 on upper face 7 to a prong 1A on upper face 11 a. distance corresponding to two holes 32 in sheet 31. It is obviously possible, however, and frequently desirable to use a transferring device of such a length that the sheet 31 will be transferred a distance corresponding to one hole 32 in sheet 31. A transferring device of a properlength to accomplish this vlast mentioned transfer is indicated in position by dotted lines Z-b on Figure 1, the transfer being accomplished in the same manner as hitherto described.

It will also be understood that the particular shape of the two ends of my transferring device 27- may be changed so that it will be able to coact with different types of prongs. It will also be understood that my transferring device -27- may be curved or S-shaped instead of straight as herein shown, for although I have shown and described a specific structure Vand form of part as an eX- emplilication of an embodiment of my invention I do not desire to restrict myself to the exact shape, size or relation of parts as various changes may be made within the scope of the appended claims.
